4 Claims.

This invention relates to storm windows and has for its object theprovision of a simple and inexpensive structure whereby a transparentweatherproof member may be placed in position at either the outer sideor the inner side of any window and prevent the entrance of strong aircurrents and drafts. It is an object of the invention to provide aflexible transparent sheet or pane which may be rolled into compact formwithin a housing or drawn out from the housing so as to cover the entireexpanse of a window at will, and it is also an object to provide meansat the sides, top and bottom of the transparent member to prevent thepassage of outside cold air past the structure to find entrance into thebuilding or room. These stated objects, and other objects which willappear in the course of the following description, are attained in sucha device as is illustrated in the accompanying drawings, and theinvention resides in certain novel features which will be particularlydefined in the appended claims.

In the drawings:

Figure 1 is a vertical section through a window having the storm windowor guard applied thereto.

Figure 2 is a horizontal section on the line 2-2 of Figure 1.

Figure 3 is an enlarged perspective view, with parts in section, of theguides for the curtain or transparent member.

Figure 4 is a detail perspective view of the upper housing.

Figure 5 is a detail perspective view of the lock or retainer whichholds the storm window in its extended position.

The drawings show a double sash window I of the usual construction. Incarrying out the present invention, there is provided a housing 2,preferably constructed of sections, one of which fits slidably withinthe other, as shown at 3 in Figure 4. This housing is constructed ofcopper or other non-corrosive metal and is generally secured to theouter side of the window frame, although it may be secured upon theinner side of the frame if so desired. The housing is located so that itbears against the head jamb 4 and the side jamb 5 and may be securedthereto in any preferred manner. The bottom of the housing terminatesshort of the back wall thereof so as to provide an opening 6 throughwhich the storm window or curtain may pass when it is withdrawn for use.On the under side of the bottom of the housing is formed a retaining lipor flange 1 in which is fitted a strip 8 of rubber or felt which bearsagainst the outer face of the curtain or transparent sheet so that theaccess of cold air into the housing and thence into the building throughthe space at the rear of the sheet will be prevented. The curtain ortransparent sheet 9 may be of any material now on the market or whichmay be later produced having flexibility and transparency and it will beof proper dimensions to entirely cover the window opening when it is Iextended, as shown in Figure 1. The upper end of the transparent sheetor curtain is secured to a spring roller I which is mounted in thehousing 2 and tends constantly to withdraw the curtain and wind thesame, as will be understood. The lower end portion of the curtain ortransparent sheet is fitted between the marginal portions of a metalplate H which clamps the sheet and holds the lower end portion of thesame smooth and extended. From the side marginal portions II, the plateis bent inwardly and upwardly, as shown at I2, at an angle correspondingto the incline of the window sill I3. The portion l2 of the clampingplate is carried inwardly a short distance and then bent upwardly andinwardly'to form the inclined lip or flange H, as clearly shown inFigure 1, it being noted that the plate is doubled medially upon itselfand then bent into the desired shape so that the portions l2 and I4 willbe sufficiently rigid and strong to withstand the effects of storms andother conditions of use. A latch post or barrel I is secured upon thewindow sill, and mounted in this barrel or on the post is a latch I6which is adapted to be turned over the flange or retaining lip 14 andthereby hold the curtain in its extended position against the force ofthe spring roller. The side edges of the curtain or transparent sheetfit within and are guided by tracks I! which are secured to the sides ofthe window frame and each of which consists of a single sheet metalmember bent to form a back wall I8 which will flt against the side jamb5 and against the outer bead IQ of the window frame. Projecting from theback wall l8 at a right angle thereto are side walls having openings 2|therethrough at intervals to receive fastening bolts 22 which areinserted I through said side walls into the head I! or other adjacentportion of the window frame so as to secure the track firmly in place.The side walls are extended beyond the bead and are expanded laterally,as shown at 23, so as toform more or less resilient jaws which are heldtogether by retaining bolts 24 inserted therethrough and equipped attheir inner ends with wing nuts 25 which are turned home against theinnermost jaw and thereby hold them toward each other. The free edgeportions of the jaws are disposed in parallelism and on their innersides carry strips 2 6 of rubber or felt which bear against the oppositefaces of the sheet or curtain 9, as shown most clearly in Figure 2 so asto hold the side edges of the sheet smooth and also cut off the passageof air or wind currents around said edges. A rubber or felt strip 21 isalso secured on the under side of the lower stop member l2, as shownclearly in Figure 1.

When the storm window is not to be used, the latch IE is turned out ofengagement with the retaining strip or flange II and the spring rollerthereupon will withdraw the curtain into the housing 2, the upwardwinding movement of the curtain being arrested by the strip I4 impingingagainst the lower edge of the back wall of the housing in an obviousmanner. The tracks terminate immediately adjacent the housing, as shownin Figure 1, so that in its retracted position the curtain will stillhave its side edges engaged in the tracks and when it is desired toagain put the curtain in use it is not necessary to lose timeendeavoring to properly enter the side portions thereof into the tracks.The retaining lip or stop flange it also serves as a handle whereby theend of the curtain may be easily grasped and the curtain drawn into itslower extended position. The device may be readily fitted to windows ofvarious widths by reason of the telescopic construction of the housingand its use will avoid the inconvenience of having to remove a rigidwindow in the spring and replacing it at the beginning of winter. Whenthe winter season is over the transparent curtain may be removed and arolling screen substituted therefor so that the housing will beavailable at all seasons and the room or building supplied with theinvention may be kept comfortable under all conditions. The storm windowis exceedingly simple in construction and may be easily operated andreadily installed at a slight expense.

Having thus described the invention, what is claimed as new is:

1. A storm window comprising a housing to be secured upon a window frameat the top of the window opening therein, a flexible transparent curtainmounted in the housing and adapted to be extended therefrom, means atthe lower end of the window opening to hold the curtain extendedthereover, tracks at the sides of the window opening comprising matingresilient jaws extending at opposite sides of the side edges of thecurtain, cushioning strips on the opposed faces of the jaws to bear uponthe side portions of the curtain, and means for tightening the jaws andclamping the curtain in a set position whereby leakage past the trackswill be prevented.

2. A storm window comprising a housing, a flexible transparent curtainmounted in the housing and adapted to be extended therefrom for closingan opening, means at the lower end of the opening for retaining thecurtain extended, tracks at the sides of the opening, said tracksincluding side walls extended medially and reduced toward their freeends to provide mating resilient jaws, bolts inserted through theextended portions of the jaws and adapted for clamping the curtain in aset position, and cushioning strips on the opposite faces of the jawsfor protecting said jaws and preventing leakage past the jaws andcurtain into the opening.

3. In a storm window, a housing adapted to be secured upon a windowframe, a flexible transparent curtain mounted in the housing and adaptedto be projected therefrom, clamping plates secured to the opposing facesof the curtain at the free edge of the same, said plates being bent toextend laterally and being again bent upwardly and inwardly to define astop flange having an inclined wall, and a latch mounted in the windowframe and adapted to engage the inclined wall of the stop flange forretaining the transparent curtain in an operative position.

4. In a storm window, a housing to be secured upon a window frame at thetop of the window opening therein, a flexible transparent curtainmounted in the housing and adapted to be extended therefrom, trackscarried at the sides of the window opening and comprising matingresilient jaws, and means carried by the tracks for clamping the jawsinto engagement with an edge of the curtain whereby leakage past saidjaws and curtain edge will be prevented.
